As the first technology verification satellite of the space-based gravitational wave detection in China, Taiji-1 has tested the high-precision space laser interferometer, the inertial sensor, the micro thruster and the hyperstatic satellite platform in orbit. The micro thruster plays an important role in the micro propulsion system. The purposes of the research are to investigate the relationship between the thrust and the interference, and then get a comprehensive understanding about the maximum effect of the thrust in Taiji-1. The transfer function between the thrust and the optical path difference fluctuations is established through the modeling, the simulation and the data postprocessing of Taiji-1. In addition, the maximum effect of the thrust in Taiji-1 is about 32 pm/Hz with an integration time of 100 s. It can be neglected compared to the requirement of 100 pm/Hz for the interferometer stability in Taiji-1.

太极一号推力与干扰耦合的探索

作为我国首颗天基引力波探测技术验证卫星，太极一号在轨测试了高精度空间激光干涉仪、惯性传感器、微推进器和超静力卫星平台。微型推进器在微型推进系统中发挥着重要作用。研究的目的是研究推力与干扰的关系，进而全面了解推力在太极一号中的最大效应。通过对太极一号的建模、仿真和数据后处理，建立推力与光程差波动之间的传递函数。此外，太极一号的最大推力效果约为 32 pm/赫兹积分时间为 100 s。与 100 pm/ 的要求相比可以忽略不计赫兹太极一号干涉仪稳定性。
